Irregular periods

What does everyone do to regulate your periods. I go months without periods. I still get them for 5-7 days. I’ve had an internal sonogram and bloodwork done and everything came back normal and my doctor told me I may just have to wait for them to regulate.(I’m 25 🤔 and have been off birth control for at-least 5.5-6 years and figured I should be regular by now). I want to get pregnant so bad but it’s so hard to track anything when I’m not getting my period regularly. I want to hear what everyone does before I talk to my gyno about it again.
